Methanol (CH3OH) Gas Sensor, 0-100ppm, 0-500ppm

This three-electrode electrochemical gas sensor detects methanol gas, offering two measurement ranges: 0~100ppm and 0~500ppm, with support for high-concentration monitoring (up to 200ppm). Featuring a simple design with an interface resistance of 5~30Ω, it is easy to use and low-maintenance, widely applied in industrial safety, laboratory research, and environmental monitoring.

Feature

• Employing the electrochemical three-electrode principle, it achieves a sensitivity of 200 ±100 nA/ppm for methanol concentration, enabling rapid detection.
• Zero drift is only 0~1 ppm, ensuring reliable and accurate performance during prolonged operation.
• Wide environmental adaptability enables stable operation across temperatures from -30°C to 50°C and humidity levels of 15~90% RH (non-condensing).
• The gas sensor can withstand maximum load concentrations up to 200 ppm with excellent linear output performance, meeting long-term monitoring requirements.
